If object A exerts a force on object B, then object B does what, according to Newton's 3rd law?
also exerts an equal force on object A
newtons first law states that ?
an object at rest will remain at rest, an object in motion will remain at motion.
1 newton is a unit used to measure ?
Force
An object at rest will stay at arrest and an object in motion will stay in motion and constant velocity unless acted upon by an unbalanced force
What is law of inertia - 1st
is the force by which a planet or other body draws objects toward its center.
What is gravity
an 80 kg skier has a force of 200 N exerted on him down the slope. Calculate his acceleration down the slope.
a =2.5 m/s2
newtons third law states
what is for every action there is an equal and opposite reaction.
f=ma what does m mean ?
mass
The more mass the object has the more net force has to be used to move it. This has to do with witch of newtons laws?
newtons second law
the force of gravity acting on matter.
What is weight
If there is a net force acting on an object, it must be
accelerating
According to newtons first law, left alone an object moves with?
constant velocity
gravity equals ?
9.8m/s2
The following quote is from which newton law, "for every action there is an equal and opposite reaction that acts with the same momentum and opposite velocity" ?
Newtons 3rd law
explains that planets are orbiting the sun in a path described as an ellipse
Kepler's First law
Friction always opposes?
Motion
In newtons second law, he defines a force to be ?
mass x acceleration
push or pull
what is inertia?
What is an objects resistance to change
This usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers
Newton's law of universal gravitation
a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving
centripetal force
The three types of acceleration?
What is increasing, decreasing, and turning
newtons second law states that the acceleration of an object is ?
What is proportional to the force acting on the mass
Newton was famous for discovering gravity because of what fruit?
